The authors present a case of lupus mastitis which was initially diagnosed following an incisional biopsy of a breast lump, with similar pathology found 2 years later after an ultrasound guided biopsy of the same lump. The woman had been diagnosed 7 years before with systemic lupus erythematosus. The radiological and pathological features are presented in this report with discussion of similar cases in the literature.
